I This invention relates to a combined can opener and tin shearsfand hasfor an object to present a structure n'whichzan efiiclent" leverage isprovided as Wellas an eificient cutting structure so that comparativelyheavy tin may be easily cut by an ordinary ,person.

' Another object of the invention is to 'provide shears in which theshearing members are so arranged that the tin or other'object being cutWill be held in substantially accurate cutting position as the cuttingedges! function. g V

An additional objectis to, prov de arpair of shears wherein the cuttingmembersare oflset from a pivotal point'so that the shears may be heldsubstantially parallel to the object being cut.

1 In the accompanying drawing Figure 1 is a side VlGWOf a pair of shearsdisclosing an embodiment of the invention. Figure 2 is a side View ofthe shears shown in Figure l but looking at the same from the oppositeside.

'Figure 3 1s a sectional View through Fig- ..ure 1 on line 3' -3.Referring to the accompanying draw ng bynumerals, 1 and 2 equal thehandles which are normally held separated by a sprin'gz held in place bysuitable posts .4 and 5 connectedto the handles 1 and 2.. Handle 1merges into What may be termed a lever 6 and handle 2 merges into alever 7, said levers being pivotally connected together by" a suitablepivotal pin-8 -Which is shown in i the form of a bolt in the drawing.Other and 12; These last named pins areshovvn I the cutting members 13and 143may be re journal members.

pivotal pins are used, namely,pins 9, 10,11

as: bolts though they could be rivets or other However, preferablygthepins 9 and 10 are bolts" in order that they may be quickly and easilyremoved so that moved at any time for sharpeningor for replacement. Thecutting member .13 I is provided With a blade'l5 and a shank'16,

said shank, having a slot 17 through which pin 12 extends. Theblade- 15is provided the blade as shown in Figure 3 whereby the I cutting portionof the cutting edge 18 Will coact With the cutting portion of the cutting. edge 19 of the blade 20. The blade20 is provided With aguide 21spaced fromthe cutting edge 19 which acts tohold the sheet metal onothermaterial-in proper position; for permitting the two cutting edge'sto cutthe same by a shearing action; I

rectly-tovvard andfrom each other so that a comparatively long sectionmay be cut at one time or a short section according to the amount ofmaterial fed between the cutting members; It willbe noted that thecutting member 20 is provided With an offset neck or'section 22 merginginto the shank23,

vwhich shank is provided with a=slit 24 through Which pinll extends.

15 is also oifsetasclearly shown in Figure? 1 so thatthe point of,cutting is appreciably below'thejpivotal p'oint8 when the device. isarranged 1n a v'ertical plane'as shown inthe drawing. This permits aflat piece of sheet metal to be" readily cut Without tilting the shearsto any appreciable extent. It also 'By the arrangement of-the pins 9 to12,

the cutting edges 18 and 19 are moved di it") The blade permits theshears to operate in substantial j ly the same mannerwvh'en cutting thetop of a tin can. The members 13 and 1 are preferably made fromcomparatively high sociated parts may be made from acheaper grade of.metal. l/Vhenever either" of the so grade steel so that the cuttingedges 18 and will function properly and for an appre}, clable time Whilethe levers 6 and 7 and as f cutting edges 18 and 19. becomes dull, theymay be readily sharpenedby removing the a members to suitable sharpeningdevice.
